“…For instance, in a two channel system, this phenomenon can be described by the model shown in Fig. 1, which depicts two direct paths and their reciprocal coupling [9]. In opposite to what is proposed in [17], in our case, the inputs of the two paths are generated from the same sound source.…”
Section: The Crosstalk Cancelation Methodsmentioning
This paper addresses the problem of adaptive noise cancellation in a multi-channel system. The proposed canceller is a recursive system, based on the Least Mean Squares filter (LMS). This method is analyzed by simulations and experimental results are given. Specifically, it is shown that this technique can improve the accuracy of ultrasound ranging and positioning systems using multichannel receivers.

“…h 11 (n) = h 22 (n) = d(n) [5,13]. According to this assumption and if the input signals are real, the two relations (2) and (3) can be rewritten as follows:…”

“…These noise components are resulting from interfering point sources, such as competing speakers, and from coherent and incoherent noise components which are emitted, for example, by household appliances and environments. [1][2][3][4][5].…”
“…The convolutive mixture uses a speech signal (French male speaker) sðnÞ and a USASI noise (United state of America Standard Institute, now (ANSI)) bðnÞ. The noisy signals are generated by the specific model proposed in [20,33], which takes into account the effect of the distance between both microphones on the signal characteristic. The latter gives simulated impulse responses h 12 ðnÞ and h 21 ðnÞ [the sampling frequency is Fs ¼ 16 kHz; the length of the impulse responses is L ¼ 64].…”
